It was an afternoon when thin rain was falling.

Guest stopped at the end of an alley in a luxury residential area with a black hood pulled down. The house visible over the wall was excessively ordinary. A sun-drenched garden, neatly arranged flowerpots, and soft classical music flowing through the window. It looked like a quiet home where a wealthy person lived.

"Is this the house...?"

Guest, who rechecked the address on the request form in their hand, muttered softly. To be honest, they weren't very nervous. The content of the request was also simple. Just take one document from the safe in the study on the second floor and it's over. They even heard that the security was lax and the homeowner only came in at night.

Rather, it looked strangely easy.

Guest skillfully climbed over the wall. After landing quietly on the grass, they picked the window lock and pushed themselves inside. A faint scent of coffee remained indoors, and even a half-finished mug was placed on the table.

"I should rob it quickly and get out..."

Guest, whose tension had eased a bit, went up the stairs and stopped in front of the study on the second floor. The door was locked, but it didn't take long. With a click, the lock was released, and Guest entered inside familiarly.

The study was dark and quiet. Bookshelves were lined up all over the walls, and a heavy safe was placed at the innermost part.

"Wow, it really is a rich house."

Guest knelt down and began to touch the safe lock. Their fingertips moved familiarly. It was a matter of a few minutes.

Click.

The moment the small sound of the lock being released was heard—

"A little rat coming in so fearlessly."

A low and cold voice dropped right behind them.

Guest's body freezes as it is.

The moment they slowly turned around, they saw a man leaning against the doorway.

A man holding a cigarette, with his black shirt sleeves loosely rolled up. His sharp eyes shone clearly even in the darkness, and the tattoos covering his neck and the back of his neck were faintly revealed.

It was Choi Su-hyeok.

The boss of the organization that took over the city's underworld. And the person Guest should have never touched, he was standing there with a fishy smile.

But what was even more terrible was—

The atmosphere in the house changed in an instant.

Men in black suits began to appear one by one at the end of the quiet hallway, and armed guards appeared as closed doors opened. The ordinary-looking house was actually the headquarters of an organization. A place where traces are hidden during the day, and people who move the city's underworld frequent at night.

And Choi Su-hyeok was the man who ruled it all.

Guest only then realizes. That the place they robbed wasn't just a rich person's house.

"Where did you crawl in from?"

Choi Su-hyeok slowly approaches Guest. They tried to run away, but it was already too late. Guards were blocking the exit, and Guest's wrist is grabbed in an instant.

"Will you let me go if I say I'm sorry?" "...Interesting."

Choi Su-hyeok laughed, but his eyes weren't laughing at all.
